bfd_hide_sym_by_version can't be used to check if a versioned symbol is
hidden. This patch adds _bfd_elf_link_hide_sym_by_version to support
both versioned and unversioned symbols by extracting versioned symbol
check from _bfd_elf_link_assign_sym_version.

My recent change to allocate values with "new" may have introduced a
small bug. In particular, the previous code allocated with XCNEW, but
the new code only clears a part of the "location" field in the
constructor. I didn't try very hard to actually trigger a bug here,
the problem remains theoretical.
This patch just arranges to initialize the entire location.
Regression tested by the buildbot.

In a review Pedro pointed out that interp::name is intended to be
read-only, and so an accessor would be a better fit. This patch
renames the field and adds a "name" method that is used instead.

This removes the interp_name function. It is only used a few spots --
one of which was only calling it on "this". It's simpler to remove
it; and should class interp become opaque in the future, it will be
just as easy to update the two remaining spots to use an accessor.

The function interp_ui_out simply calls the interp_ui_out method.

require callers to be more explicit.

Our interpretation of the layout of floating-point general registers
(FGRs) in o32 MIPS/Linux core files is different from how the kernel
makes them, affecting the CP0 Status.FR=0 aka FP32 mode (we don't
currently support the CP0 Status.FR=1 aka FP64 mode with the o32 ABI).
In the FP32 mode pairs of consecutive even/odd-numbered 32-bit registers
are placed together as 64-bit values in even-indexed 64-bit slots
corresponding to the even index, leaving the odd-indexed 64-bit slots
unused. These 64-bit values are stored according to the endianness in
effect, which is how the MIPS II SDC1 instruction would store them.
It has always been like that with the Linux kernel for MIPS II and
higher ISA processors, which are the vast majority ever supported, as it
is indeed SDC1 that the kernel uses to store FGRs in a floating-point
context.
With MIPS I processors, which lack the SDC1 instruction, a layout that
we expect used to be used long ago, but it was corrected for consistency
with newer processors back in 2002, with `linux-mips.org' (LMO) commit
42533948caac ("Major pile of FP emulator changes."), the fix corrected
with LMO commit 849fa7a50dff ("R3k FPU ptrace() handling fixes."), and
then broken and fixed over and over again, until last time fixed with
commit 80cbfad79096 ("MIPS: Correct MIPS I FP context layout").
Consequently the values we see in FP32 core files or produce with the
`gcore' command are different from those obtained from the same FP
context of a live process, e.g. with a big-endian configuration these
live values:

Notice how values from odd-numbered registers are shown in corresponding
even-numbered registers and how dummy 0x7ff80000 NaN values, which the
kernel places in unused slots, are reported in odd-numbered registers.
Correct our intepretation then, to match the kernel's. As it happens
the o32 FGR core file representation matches that used by the `ptrace'
PTRACE_GETFPREGS request, which means our 64-bit handlers can be readily
used, as they already correctly handle the differences between o32 FP32
mode vs n32/n64 representations.
Adjust comments accordingly throughout, in particular remove a reference
to the r3000/tx39 MIPS I processor peculiarity, long irrelevant.
Add a test case to verify correctness. Avoid GCC bugs and limitations
in the test case where possible; the test case still fails to build with
GCC 8 and the o32 FP64 mode (i.e. with `-mips32r2 -mfp64' options)
giving:

mips-fpregset-core.c:66:3: error: inconsistent operand constraints in an 'asm'
asm (
^~~
(GCC PR target/85909), but that is not a concern for us as yet, because
as noted above we do not currently support the o32 FP64 mode anyway.

Complementing commit 280ca31f4d ("Add test for fetching TLS from

where supported.
This verifies not only that our core dump interpreter is consistent

avoiding a possible case where our interpreter would be bug-compatible
with our producer but not the OS and it would go unnoticed in testing.

gdb/ChangeLog:

* darwin-nat.h (darwin_nat_target::create_inferior): Mark with
override.
struct complaints now just holds a single enum value, so remove it and
symfile_complaint_book and replace it with a global variable.

* complaints.c (struct complaints): Remove.
(symfile_complaint_book): Remove.
(series): New global.
(complaint_internal): Update.
(clear_complaints): Update.
At this point, struct complain is just holds a key, a value, and a
"next" pointer to form a linked list. It's simpler to replace this
with an unordered map.

* gdb.gdb/complaints.exp (test_initial_complaints): Simplify.
The file and line handling in complaints.c wasn't used once
internal_complaint was removed. This patch removes all the related
code.

* complaints.c (struct complain) <file, line>: Remove.

vcomplaint now has a single caller, so merge it with that caller.

* complaints.c (vcomplaint): Remove.
(complaint_internal) Merge in contents of vcomplaint.
Now that there's only a single reason for a complaint to be emitted,
this removes "struct explanation" and changes vcomplaint to emit the
desired messages directly.

* complaints.c (struct complaints) <explanation>: Remove.
(symfile_explanations): Remove.

After the previous patch, the "noisy" parameter to clear_complaints is
no longer used, so this patch removes it.

* complaints.c (clear_complaints): Remove "noisy" parameter.

* gdb.gdb/complaints.exp (test_empty_complaints): Update.
I couldn't find a way to get complaints to use a couple of cases, and
the difference between the actual printed output for these cases was
minimal anyway. So, this patch removes a couple of constants from
complaint_series, plus the associated code.
gdb/ChangeLog
2018-05-23 Tom Tromey <tom@tromey.com>
* complaints.c (enum complaint_series): Remove FIRST_MESSAGE,
SUBSEQUENT_MESSAGE.

2018-05-23 Tom Tromey <tom@tromey.com>
* gdb.gdb/complaints.exp (test_serial_complaints): Remove.
(test_short_complaints): Update.
I happened to notice that gdb has both complaint_internal and
internal_complaint. The latter is unused, so this patch removes it.

2018-05-23 Tom Tromey <tom@tromey.com>
* complaints.c (internal_complaint): Remove.
* complaints.h (internal_complaint): Remove.
Currently, the function used by gdbserver to parse integers from
received File I/O commands will detect overflow and fail for any value
over 0xfffffff. Among other things, this has the effect of limiting
the file offsets for reading or writing to about 268MB which can be
insufficient for particularly large libraries.
This change allows the parsing of integers up to the true maximum
positive value of 0x7fffffff, increasing the file size limit to about
2GB.
gdb/gdbserver/ChangeLog:

PR server/23198
* hostio.c (require_int): Do not report overflow for integers
between 0xfffffff and 0x7fffffff.
This fixes gdb.base/remote.exp regressions caused by the previous
commit to the testcase, when tested with
--target_board=native-extended-gdbserver. For example:
...
show remote memory-write-packet-size
The memory-write-packet-size is 0 (default). Packets are limited to 16383 bytes.
(gdb) FAIL: gdb.base/remote.exp: write-packet default
...
With that board, GDB connects to GDBserver at gdb_start time, so GDB
is showing the actual remote/gdbserver packet size limits.
Fix it using the usual "disconnect" pattern. While at it, there's no
need to start GDB before compiling the testcase.
gdb/testsuite/ChangeLog:
2018-05-22 Pedro Alves <palves@redhat.com>
* gdb.base/remote.exp: Only gdb_start after compiling the
testcase. Issue "disconnect" before testing "set remote" command
defaults. Issue clean_restart before running to main.
